Doran and Kendall Zimmerman conclude that "the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes." The challenge now, they write, is how to effectively communicate this to policy makers and to a public that continues to mistakenly perceive debate among scientists.

At least 70 skeptical scientists are meeting in New York City this week to dispute that humans are contributing to global warming. Wow, 70 of them. No doubt, conservatives will rally to sing their praises, pretending that they have a large consensus among scientists, which they do not.

Total attendance at the event, sponsored by the Heartland Institute, is expected to be around 800, but as you can see (via the links below), very few of them are experts in the field.

Meanwhile, a recent survey of over 3,000 earth scientists shows that 82 percent of them believe that human activity has been a significant factor in changing mean global temperatures.
